Conversion of Lehr's Damping into Rayleigh Damping

Product Feature

Calculation with consideration of a damping ratio (or Lehr's damping) is not possible in the direct time step integrations. Instead, the Rayleigh damping coefficients must be specified by the user.

In technical literature, the given damping ratio for specific construction forms is in many cases only a rough approximation of the real damping ratios. In RF-/DYNAM Pro - Forced Vibrations, it is possible to use the value of damping ratio to determine the Rayleigh damping. This may occur at one or two natural angular frequencies defined by the user.
